Error: Cannot find module 'webpack-dev-server' for running 'webpack serve'.

[JohnAdam-123]

I am trying to running openMCT-yamcs project in Virtual Machine but whenever I run npm install or npm start I get error as an output that webpack module is not found.

How can I solve this, any ideas please?

Hi @JohnAdam-123 ,

We need a bit more information to debug this further:

1. Which virtual machine are you using and does it have access to the internet to download npm packages?
2. Which version/branch of openmct-yamcs are you trying to install? Is it master?
3. What version of node are you using? Is it greater than node 18.14.2 and less than node 22?
4. At which step of the README are you getting the errors above?
